UNITED STATES VILLIAM II. LUNG-REN, OF BALTIMORE, HARYLAND.

IMPROVEMENT IN HOT-WATER HEATERS.

Specification forming part of Letters Patent No. 116,608, dated July 4, 1,371.

To all 'whom it may concern:

Be it known that I, XVILLMM H. LUNGREN, of Baltimore, in the countyot' Baltimore and State of Maryland, have invented a new and improved mode of getting circulation of water in hot-water heating-pipes and preventing explosions of same, of which the i'ollown is a speciiieation:

The nature of' my invention consists in providing4 the upper part of' hot-water pipes in heating fixtures with a iioat-valvo so arranged as to allow any steam that may be generated to escape into a receiverprovided above, where V it may be condralsed and return VVtothe pipes; the valve being so arranged asto be lifted by the water Should it rise to the bottom, and when lifted to make a joint at top so no water may escape. The receiver above the valve is iilled with sponge or other material which will absorb' the steam that may escggewabov alvefand when condensed bvY remainin i Lompge it will return to the pipes, thus preventi ng aix 'vf/*escape or wast-age of water, and at the same time preventing air from entering' thc`1 es. A

To enable others skilled in the art to make and use my invention, l vwill describe its construction and (mer-ation.

A is the housing' or cage to contain valve X, which cage is provided with seat Y on which the valve X rests, and makes a joint when down.

The valve X is also provided with smooth curved upper side, which, when raised, will make a ljoint on housing A. The cage A is pro\f'i .led with connecton M, by which it is fastened into the highest point of the hot-water pipes. Above thevalve X, connected with the cage A, is a covered cup or receiver, B, connectin with valve-cllamber A by small openin Z Z. The receiver B is iilled with sponge or other .material that will retain moisture. The cap of cage B is perforated toadmit cool air to act on the stealn-saturated sponge and condense it. The c: yge and valve with receiver being attached to the hot-water pipes at their highest point, the valve X will remain stationar)r until Steam is generated, when it will rise slightly and allow it to escape into receiver B above, where it will be absorbed by tl le sponge, and when condensed will run back into the pipes; but should the water rise it will tloat the valve and raise ituntil itcomes in contact with the upper bea-rin g N, in upper end ot cage A, where it makes a ,joint and prevents any water escapin I claim as' my invention and desire to secure by Letters Patent- 1. The valve X working in cage A, substantiallyv as and for the purpose hereinbeiorc set forth. 4

2. The receiver and condenser BB, substantially as and for the purpose before set forth.
